ABSTRACT:
A hydraulic control system including a torque sensor for producing a hydraulic signal proportional to torque transmission includes a control chamber or cavity which is supplied with fluid pressure through a plurality of restrictions or orifices from a pressure source. An accumulator is disposed between two of the restrictions such that the torque signal proportional to the pressure in the cavity is modulated or otherwise adjusted to accommodate the changing torque levels which occur as transients during the ratio interchanges in an automatic transmission.
